Definitions

  • the present invention relates to a manufacturing method and a manufacturing apparatus for a flexible hose used for a vacuum cleaner and the like, and in particular, a tube or a conducting wire for returning the exhaust of the cleaner to a suction tool or the like.
  • the present invention relates to a method for manufacturing a flexible hose having a tube for storing the inside of the hose.
  • Patent Document 1 An example of such a flexible hose is described in Patent Document 1.
  • Patent Document 2 describes a method for producing such a flexible hose.
  • Patent Document 2 after introducing a tube coated with a thermoplastic adhesive into the hose, the hose and the tube are bonded and integrated by crushing the entire hose, and the tube is integrated inside the hose.
  • a method of obtaining a flexible hose provided is disclosed.
  • Patent Document 1 Japanese Patent Laid-Open No. 6-201073
  • Patent Document 2 European Patent EP1011960 (B1) Publication
